This invention relates in general to snow plows for removing snow from roads, streets, or highways, the apparatus .embodying a scoop like formation into which the snow is i j delivered to be conve ed therefrom and discharged to one' side o the `road or path made l bythe advancement of the plow, and one of the Objects of the invention is to provide im proved means for preventing'the packing of the snow within the scoop and for keeping the snow in motion at all times during the advancement of the plow.

v the several parts, hereinafter more fully detion and is preferably provided scribed and claimed and shown in the accompanying drawings illustrating this invention, and in which Figure 1 is a front elevation taken on line 1-1, Figure 2, of a plow of this character constructed in accordancewith the principles of this invention.

Figure 2 is an end elevation taken on 'line 2?-2, Figure 1.

Figure 3 is a line 3,3, Figure 1;

Figure 4 1s a detail sectional view taken on line 4-4, Figurelfif f `Referring more particularly to the draw- ,ings the numeral 10 designates generally a scoop like formation which is arranged at the front of a supporting struct-ure (not shown) 1to be forced into the snow bank as the vehicle' advances.Y

-of any desiredforma- This scoop may ibe only with a bottom 11 and back wall 12. Carried bythe scoop and preferably by the rear wall l12 thereof, are bearings 13-14. In the bearing 13 is journaled an annular member 15 which is'preferably provided with spokes 16 and a hu like portion 17.

Journaledin the bearing 14 is a rotatable member 18 4having a hub '19, which latter forms a bearing for one extremity 20 of a shaft 21. The other end 22 of the shaft 21 is journaled in the bearing 17 in the member 15.

detail sectional view taken on ameter that the blades 30 will b e disposed The bearings 13 and 14 are so disposed with respect to each other that the bearing 13 will be 1n a higher plane than the bearing 14 so that'the shaft 21, which is journaled in the bearings 19 and 17, will be inclined upward- Propeller blades 23, preferably of a spiral conguration, are connected with the shaft 21 to rotate therewith and the shaft isrotated preferably by means of a gear wheel 24 secured to the shaft 21 and with which gear 24 a gear 25 meshes, the latter in turn meshlng with another gear 25 on al shaft 26.

The shaft 26 is journaled in suitable bearings 27 and receives its motion from any suitable source of power (notshown) preferably through the medium of a drive belt 28 passing over a pulley 29 that is connected with the I shaft 26.`

The shaft 21' may be of any desired lengt-h according to the distance between the members 15 and 18 and these members are spaced from each other preferably for a distance substantially equal to the width of the scoop like formation 10 so that the shaft 21 will extend substantially thereacross.

' Connected with the members 15 and 18 are blades 30 which are secured by their ends to the members 15 and 18. These blades30 are preferably comparatively wide with respect to their thickness and are twisted throughout their length and shaped' to' form cutter blades.

The members 15 and 18 are of such a dion the outside ofbut in proximity tothe periph'ery of the spiral blades 23.

' posite to the direction of rotation of thel members 15'-18 and the blades 30.

The blades 30 together with the members 15 and 18 are rotated preferably'by means of a gear vwheel formation 31 connected with the member 15, and meshing with'the teeth of the gear 31 is a gear 32 carried by the shaft 26.

It will therefore be seen that when the shaft 26 is rotated the blades 23 will be ro-` tated in the opposite direction with respect to the blades 30hy reason of the fact that the blades 30 are driven by a direct gear connection 31--32 with the shaft 26, while th'e blades 23 are driven indirectly from the shaft 26 through the medium of the train of gears 21-25 and 25.

In use and when the snow enters the scoop like formation, the blades 30 will chop up or disintegrate the snow and prevent it rom packing, and at the same time the snow will pass between the blades 30 to the spiral conveyor blades 23, the latter operating upon the snow fed thereto to convey and discharge the same through the member 15, as indicated by the arrows in Figure l, and to the side of the road' or path.

The blades 30 also operate to produce a conduit or passage in the snow which is piled in the scoop l0 and thereby form an exit through which the snow is driven by means of the conveyor blades 23.

While the preferred form of the invention has been herein shownand described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new is 1. A snow plow including a scoop like structure, a conveyor disposed within and transversely across the scoop for delivering the snow to one side thereof, means encompassing and rotatable about the conveyor for disintegrating the snow and feeding the same to the conve or therethrough, and means for operating t e conveyor and the first said means.
